I always though the Corprus was weak in morrowind, so i have made a list of ideas to make it better, but i just got my CK working and im trying for clutter so I hope someone more experienced sees this.

Because you are the nerevarine does that mean you are not affected by it as much
Fyr has a theory that corprus is in fact not a disease, but rather a divine blessing that most mortals can't handle, pointing to the fact that the victims are completely immune to other diseases and don't age
so maybe that is why it only drops your stats by 1, but if not it should drop you stats by 30 or 40. or make you into a corprus beast (which the PC will see as just dieing and will have to reload.

So far there are only 3 types of corprus beast, Ash creatures, Corprus stalker, and Lame corprus
ash creatures are Dunmer, and Stalkers and Lame ones are human, so why not Argonian and Khajit types to add diversity.
Skyrim doesn't really have
Skyrim doesn't really have those sorts of stats though. I'm sure they have a version suited for Skyrim's engine in the works.
